Background

Leo was raised in a rough part of Detroit. The only thing he had in life was his mom and his dog Rocky as his father left him when he was young. His mom did what she could to get by but it was hardly enough. The times got tough and his mom had to abandon Rocky. Leo felt lost after this because Rocky was the only thing in life he wanted to help. Leo found his place in the PAU as he felt there was a real sense of comradery and a sense of purpose he could work towards. He has been allied with the PAU as a soldier since he found them.
